Abstract: An optics-integrated confinement apparatus is provided. The optics-integrated confinement apparatus includes a first substrate, a plurality of electrical components formed on the first substrate, and an on-chip beam delivery system. The plurality of electrical components define a confinement apparatus configured/operable to confine one or more quantum objects. The on-chip beam delivery system includes a waveguide, a coupler, and an optical element. The coupler is configured to couple an optical beam out of the waveguide and toward the optical element. The optical element is configured to modify a polarization of the optical beam and direct the optical beam toward a target location defined by the optics-integrated confinement apparatus.

Abstract: A composite confinement apparatus assembly is provided. The composite confinement apparatus assembly includes a quantum object confinement apparatus and a photonic platform. The confinement apparatus includes one or more electrical components and is fabricated on a confinement apparatus substrate. The photonic platform includes one or more photonic components that are hosted by a photonic platform substrate. The photonic platform substrate is mechanically coupled to the confinement apparatus substrate to form the composite confinement apparatus assembly.

Abstract: An efficient and portable method for remote detection of a target mineral material through frequency domain fluorimetry, a detection technique that measures the time lag between absorption and emission of photons, thereby determining the lifetime of said target mineral material. As claimed and disclosed in the present invention, mercury vapor lamps, a common source of industrial facility lighting, emit radiation that overlaps the UV/blue absorption spectrum of many fluorophores and may be used as an efficient and portable excitation source for remote frequency domain fluorimetry.

Abstract: A bi-directional pulsed ring laser that produces bi-directional light pulses that interact in such a way that they are phase conjugated. A nonlinear substance, such as a nonlinear crystal or fluid, that has an index of refraction that is dependent upon light intensity is located near a beam waist of the laser cavity to provide a self-lensing effect. Methods for reducing dead band beyond observable limits are also provided. The increased sensitivity of the bi-directional pulsed ring laser provides application in detecting magnetic susceptibility by detecting the change in phase between the arrival times of the bi-directional pulses at a modulator and the electrical signal of the modulator to determine the change in frequency of a coil that has magnetic susceptibility.
